Letters Patent No. 110,188, dated December 20, 1870.

IM PROV-EMENT IN LAM P-WICKS.

The Schedule referred to in these Letters Patent and making part of the same.

I, PHILANDER BAKnR, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Lamp-Wicks, of which the following is a specification.

My invention relates to the Hat hollow wicking ordinarily used in kerosene burning and other lamps.l It has for its object tofll the hollow part ofthe Wick with Aa thin strip of metal, perhaps brass or copper, which is rstplaced in the wick, and then by a proper mechanical contrivance, punched full of numerous minute holes, whose ragged edges take firm hold ot' the wicking 'and prevent its withdrawal.

This device gives strength and rmncss to the wick, enabling the ratchet-Wheel'of any ordinary burner to more it squarely up and down the wicktube.

The end of the metal strip, projecting with the wick' at the top of the wick-tube, offers a. largersurface for the oil or illuminating fluid, and, becoming heated, assists in more rapidly Iconsuming the carbon, whereby a better light is produced with the same lamp and illuminating fluid ata very triiling expense.

Description of thc Accompanying Drawing.

Figure l is a view of the wick in operation, with a portion ofthe pervions covering cut away to display the metallic core.

Figure 2 is a transverse section on the linc x x.

Figure 3 isA a view of the wick surrounding thecore.

General Description.

In the drawing- 'A represents the cotton-wicking.

B, the thin strip of metal, punctured with numerous holes.

O may represent any ordinary burner with its milled thumb-Wheel D.

In manufacturing'my invention itwill be necessary to first insert the metallic core in the hollow wick, then puncture it through the loose bers of the wicking; the ragged edges of the punctures will then prevent its being removed.

In ordinary wicking the ratchet-wheel is apt to wear through' the cotton fibers, wheuit will be found impossible to move the wick up or down.

My invention removes this didculty by furnishing a rm hold to the cogs vof the ratchet-wheel.

Claim.

I claim as my invention- The lamp-wick, composed of the metallic core B, and pervious covering, when constructed so as to operate substantially as shown and described.
